17 Claims.

This invention relates to improvements in selective printing machinesand refers specifically to a machine for automatically printing frompredetermined master printing cards, said cards being selected from astack of master cards which may contain the selected cards in sequentialor non-sequential order; I

In commerce certain categories of information -are frequently maintainedon cards constituting a file of pertinent information relating to themembers of the category. It is frequently desirable to select from saidmain file, cards which may be common to a sub-category and print therelevant information as to said sub-category.

As an example, which, however, is not to be construed in a limitingsense. the main file may comprise names and addresses of prospectivecustomers of a predetermined business, forlnstance, automobile owners ofa given State. in the normal course, these cards would ordinarily bearranged alphabetically. However-,; in a certain instance it may bedesirable to select the owners of 1940 Fords, for example, who maylive'i'n a predetermined county of the State, and to print their namesand addresses in sequential order.

The present invention is directed broadly to a machine for accomplishingthis or a similar task, and one of the objects of the invention relatesto the provision of such a machine which simply and efficiently performsthis task.

The example hereinbefore set forth involves a triple breakdown of themain file. However, the desired sub-category may involve only a singlebreakdown of the file or may involve a more limited breakdown. Y a

As another object of the invention a main file may be broken down onceor any plurality of times and the desiredsub-category selected andprinted from in a single pass of the main file through the machine, andthis is accomplished merely by depressing one or more of a plurality ofselector buttons, I p

A further feature of, the invention resides in the provision of meansfor moving a web of paper upon which the names and addresses may beprinted from the selected cards in sequential manner with a desired oroptional spacing between sequentially appearing names and addresses.

Another important feature of the invention rethis invention.

sides in the provision of a card feeding mechanism which urges each cardof the main die forwardly with equal force regardless of whether thecard is to be printed from or not, whileat the same time preventing thenon-selected cardsflfrom bei'n'g smudgd. 1 g

A further feature of the invention resides in automatic timed means formoving the web during the printing operation while maintaining the webstationary when non seiected cards ass the printing station.

Another important feature of the invention comprises a feeder mechanismwhich simultaneously urges the printing cards forwardly While performingthe function of aetiiating the selecting mechanism, that is, both innermechanism and cards are moving during; the actuation of the selectingmechanism and relative motion of the feelers and cards is notcontemplated.

Referring in detail to the drawings, I indicates a table or support uponwhich the machine comprising the concepts of the present invention ismounted. The table I is provided with legs 2 which carry a flatsupporting top 3.

An electric motor 4 is mounted upon the lower face of the top 3 and issecured thereto by means of bolts 5 or the like. A pulley B is mountedupon the motor shaft 1 and an endless belt 8 is adapted to be trainedaround the motor pulley 6. A

hanger 9 is suspended from the table top 3 and a shaft 19 is supportedthereby. The shaft in carries a pulley H around which the belt 8 istrained. A second pulley I2 is also carried upon shaft iii and anendless belt I3 is trained around pulley l2. A pulley wheel I4 iscarried upon shaft 15 and a second pulley I6 is loosely carried uponsaid shaft. A conventional clutch mechanism 11 operated by means ofhandle I 3 functions to engage or disengage the pulley [6 from shaft l5.

An endless belt is is trained around pulley l6 and functions to rotatepulley 20 carried upon shaft 2|, journalled in frame 22 which latterconstitutes the frame of the machine proper. A

, wheel 23 is also carried upon shaft 2| and can be employed to manuallymove the shaft 2| independently of the driving mechanism, hereinbeforedescribed, whereby to permit relatively slow motion to be imparted tothe moving parts of the machine so as to facilitate the proper timing ofthe various elements of the machine.

As shown best in Figs. 2 and 15, shaft iii ex tends transversely acrossthe frame 22, and said shaft carries at its opposite end a pinion 2which meshes with spur gear 25 which is keyed to shaft 26. Shaft 26extends entirel across frame 22 and carries a spur gear 21 upon itsopposite end. A similar spur gear 28 is keyed to shaft 25 adjacent thespur gear 25.

Spur gear 28 meshes with pinion carried upon stub shaft 3!] journalledin one of the side frame members. A similar pinion 3! is carried upon astub shaft 32 which is journalled in the opposite side frame member. Acollar 33 is keyed to the inner end of the shaft as and a similar collar24 is keyed to the inner end of shaft and shafts 30 and 32 are in anaxial alignment. A segment 35 is carried upon collar 33 and a similarsegment 36 is carried upon collar 3G, said segments, when the machine isin proper adjustment being in alignment with each other transversely ofthe machine. The purpose of these collars and the segments carriedthereby will be hereinafter more fully described.

A pinion 31 is keyed to shaft 23 and meshes with a spur gear 38, shownbest in Figs. 1 and 15. Spur gear 38, in turn, meshes with a spur gear33, both gears 38 and 39 being idler gears. Gear 33 meshes with an idlerpinion as and gear 39 meshes with an idler pinion i I. Pinion so mesheswith gear 42, which is keyed to shaft shown best in Fig. 16. In similarfashion pinion meshes with gear 44, which is loosely carried upon shaft45.

A sprocket wheel 46 is keyed to shaft is and is adapted to drive asprocket chain 37, as shown best in Figs. 1 and 16. A shaft 43 isjournalled in frame 22 and a sprocket wheel E9 is mounted upon saidshaft. Gear 50 is rigidly connected to the sprocket wheel 49 and saidgear is rotated by means of. the engagement of sprocket chain 41 withthe sprocket wheel 49. A shaft Si is mounted upon frame 22 and a gear 52(Fig. 2) is loosely mounted upon shaft 5 i, said gear meshing with gear50 whereby motion is imparted to the gear 52. A sprocket wheel (notshown) is rigidly connected to gear 52, both sprocket wheel and gearbeing loosely positioned upon shaft i, and a sprocket chain 53, shown:best in Fig. 16, is trained around said sprocket wheel. sprocket chain53 functions to drive sprocket wheel 54 loosely mounted upon shaft 55.

Referring particularly to Fig. 15, a sprocket wheel 56, which may beformed integral with gear 21, is keyed to shaft 26. A sprocket chain 51(Fig. 2) is trained around sprocket wheel 55 and is driven thereby. Thesprocket chain 5'! in turn is trained around sprocket wheel 58, shownbest in Fig. 17, said sprocket wheel being keyed to. cam shaft 59 whichis journalled in the frame 22.

A hopper 50 is carried by members iii which are, in turn, connected bywebs E2 to frame 22.. Hopper 60 is of rectangular shape incross-sectior1 and is open at its top to receive a plurality of cards 53and hold them in' a vertical stack 5d. A flange is positioned at thebottom of the hopper and extends along one side of the hopper wherebythe stack is supported on that side of the hopper. The opposite side ofthe stack is normally supported by a separator blade 96,

which will be hereinafter more fully described.

Referring particularly to Figs. 9, l and 11,

a transverse support 6'! extendsYbetweenopposite frame membersZZadjacenthoppertli. The'support 6! is provided with slots 68 (Fig. 2);one

adjacent each end thereof, whereby the supportnormally stationary withrespect to sleeve l3,

being adjustable to a desired position with respect to said sleeve bymeans of the knurled nut -75 threadedly engaged upon the end of bolt M,the nut being integral with a sleeve "19 which bears upon a spring (notshown) carried within sleeve I3.

Bolt 74 is rigidly secured to a cylindrical collar 7? and slidab lymounted upon said collar is a sleeve I8. A projection I9 is formedintegral with the slidable sleeve 18 and is adapted to slidably engagein a slot provided in the casting ll, as shown best at 80 in Fig. 10.sleeve 38 is constrained to move axially with respect to collar 3"! androtary motion of sleeve 19 with respect to collar 57 is prevented.

A member 81 is integrally formed upon sleeve l8 and extends laterallytherefrom. Apin 8-2 is 'loosely'positioned-in the member 8i and aknurled nut 83 is threadedly secured to an end thereof. On the oppositeside of the member 8i, pin 32 is embraced by a coil spring 84, saidspring being confined between member 8i and a bar '95 (Figs. 6 andcarried at the end of pin 32. An L-shaped bracket 56 is adjustablysecured, by means of bolts 81, to the bar 85, the bracket being slotted,as shown best at 88 in Fig. 6. A plate 89 having a flange 90 isadjustably'secured to the cross-portion of the bracket and blade S6 isalso secured to said bracket, the plate 39 and blade 66 being secured bybolts or screws gr. I

An abutment plate 92 is rigidly secured to the slidable sleeve I8 and isprovided with a contact "surface 93. A hearing bracket 94 is supportedby the crossfmemb'er 51 and a shaft 95 is rotatably journalled in thebracket 94, said shaft also being journalled in the casting ll An arm 96is rigidly secured to an end of said shaft and is adapted to makecontact with the surface 93 of plate 92 when shaft. 95 is rotated; Atension spring 9'! is anchored at one end upon the plate 92 and at theopposite end to arm 99 said spring normally urging said two partstogether.

The separator 70, in itself, forms no part of the present invention, andis described in detail only to indicate its function as used inconjunction with the present invention and thereby more clearlyillustrate the present invention.

Referring particularly to Fig. 9 of the drawings, a cam 98 is rigidlysecured to the'cam shaft 59. A bell crank lever 99 pivoted upon shaft190 is positioned adjacent the cam 98, one arm IOI of said levercarryinga roller I02 which functions as a follower for the cam 98. Theother arm I03 of the lever 99 is pivotally connected as at I94 to linkI05, the oppositeend of whichis pivotally connected to anarm ,I 06 (Figa10) which, in turn, is rigidly secured to shaft 95'.

In this manner itransversely across the frame of the machine. A.

-As =has*been hereinbefore described, the stack 641 of cards 63carriedin hopper 60, is supported by flange 65 and blade.- However,cards '63, as will be hereinaftermore, fully described, are removed' inseriatim from the bottom of. the stack 64. In order to effect suchremoval the blade 66 is withdrawn ,momentarily from its supportingposition, as, shown best in Fig. '9.

It can readily be seen that during the major portion of the revolution'of cam 98, the follower I02 rides "uponithe circular -portion of saidcam and hence, blade fifipduring such phase of operation, is positioned.in supporting relationship to the stack-'64, as shown best in Fig. '6.In this position, arm I03'of the bell crank lever '99 is .moved to itslimited counterclockwise position,

as viewed inFig. 6. With the arm I03 in this position, arm I06 is swungto its limited clockwise position, and, in turn, the contact arm 96 isswung away from the contact surface 93 of blade 92. When arm 96 swingsto this position .it exerts tension upon spring 91 and as a resultsleeve 18 is moved to the right, as, viewed in Fig. 6, until the end ofsaid sleeve contacts abutment I I I carried uponthe end of bolt 14.

It will be noted that the high point of cam 98 is rather peaked, thepeak spanning a relatively small angle of the revolution of the cam.When the peaked portion of cam 98 contacts follower I02, the arm 99 isrocked so as to move arm I03 into its limited clockwise position, asviewed in Fig. 9. With this motion, arm I06 is rotated in acounterclockwise. direction and contact arm 96 moves into contact withthe surface 93 of plate .92. This movement of arm 96 causes sleeve 18 tomove to the left, as viewed in Fig. 9, and hence, blade 66 ismomentarily removed from its supporting relationship with respect tostack 64.

It is to be understood that the movement of blade 56 is momentary andthat the motion is a reciprocating one wherein the blade moves outwardlyand inwardly very rapidly. With the assistance of auxiliary mechanism,which will be hereinafter more fully described, the blade 56 separatesthe lowermost card from the stack 64 and then resumes its supportingposition with respect to the remainder of cards 63 in said stack.-

To effect the removal of the lowermost card 63 from the bottom of thestack 64, a vacuum arrangement is employed. This arrangement comprises asucker tube II2 having a mouth .or open end II3 which opens in a planesubstantially parallel to the plane of the lowermost card at the phaseof operation just prior to removal of the card, that is, immediatelyafter the sepa, to-an'arm ll'lfhereinafter more fully de scribed.

In operation, the mouth or openend I I3 of the sucker tube II2 describesor traces a compoundmost card 63, said mouth first moves downwardly;thence backwardly; thence forwardly and upwardly to its originalposition immediately beneath the lowermost card of the stack. Indescribing this path the vacuum is controlled, as described hereinafter,to remove the card from the stack, deliver it to a positioning mechanismand release it.

The mechanism for imparting the vertical component of the motion of themouth II3 will now be described.

Referring particularly to Figs. 5a and '7, a cam H8 is rigidly mountedupon cam shaft 59 adjacent cam 98. A rocking member II9 is pivotallymounted upon the pivot shaft I00 and comprises a hub having threecircumferentially spaced, laterally offset arms. The arms comprise,follower arm I2I which carries follower roller I22, reaction arm I23 andoperating arm I24. Reaction arm I23 is pivotally connected at its end,as at i255, to rod I26. The rod I25 is slidably positioned within asleeve I2'I which latter is pivotally connected to anchor rod I08, as atI23 in Fig. '7. A compression spring I29 embraces rod I26 and urges armI23. in a clockwise direction, as viewed in Fig. 7, thereby maintainingfollower I22 in contact with the surface of cam I I8.

Operating arm I24 carries a slotted extension I35 which is securedthereto by bolt I3I and an internally threaded sleeve I32 is pivotallyconnected to the extension I30, as at I33 in Fig. 7. By means of theslot in the extension I35 the pivotal connection I33 may be adjusted toa desired position along the length of the extension.

Block i It carries an extension I54 and a transversely extending lug I35(Fig. 52) is pivotally mounted adjacent the end of said extension. Athreaded link I36 is connected at one end to lug I35 and is threadedlyconnected at its opposite end to sleeve I32.

it can readily be seen that the mouth H3 is moved by the rotation of camIIB in a substantially vertical direction, neglecting angularity, but,as will be hereinafter more fully described, this motion is compoundedby the action of the pivot I It of block I I4 which is also movable. Theinstrumentalities for moving the pivot IIG will now be described.

Referring particularly to Figs. 5, 5a and 17, a cam Isl is mounted uponshaft 59, and a cam follower roller I35 is adapted to ride upon thesurface of cam I31. The follower roller I38 is carried at the end oflever arm I39 which is pivotally mounted intermediate its length uponshaft ltd. The opposite end II! of lever arm lie is pivotally connected,as at III; in Fig. 5a, to block H4. A compression spring assembly isanchored at one end, as at I31, to anchor bar we and is connected at theother end to arm I 11 whereby the follower I33 is maintained in contactwith the face of cam I31.

It can readily be seen that as cam shaft 59 rotates, the arm II'I swingsthe pivot point H5 in a substantially horizontal direction as viewed inFig. 5. This movement of the pivot point I I6 imparts a horizontalmotion to the tube I I2.

It will be noted that the motion imparted to the mouth H3 of the tube H2is the resultant of movements imparted by cams H8 and IN, said movementsbeing superimposed upon each other, cam IIZS moving the block II and,hence, the tube H2 about the pivot point H5 and the cam I3? moving thepivot point itself.

An arm I45 is rigidly secured to shaft and a coil spring MI is anchoredat one end upon pin I42 mounted adjacent the end of the arm Hit. Theopposite end of the coil spring id! is anchored upon hook I53 carried atthe end of the extension I35. The coil spring MI is normally in tensionand functions to bias the connection comprising tube i32 and rod l35against any play which may occur in the various pivotal connections.

A fourth cam Hi l is secured to the cam shaft 55 and a follower rollerI55 is adapted to ride upon the surface of said cam. The roller I55 iscarried upon an end of bell'crank lever it which is pivoted intermediateits length to the shaft I55, and roller I45 is maintined in contact withthe face of cam I44 by tension spring Hi5 connected between anchor barWe and arm I 55."

The opposite end of the lever Iii is pivotally connected as at I i'I,Figs. 5 and 5a, to a pusher member I43. The pusher member is supportedintermediate its length upon a pair of oppositely disposed arms 59, onlyone of which is shown, the pusher member being pivotally connected atI55. The arms I59 at their opposite ends are loosely carried upon shaft2 i.

Referring particularly to Figs. 24L, 25 and 26, the structural detailsof the pusher member I55 will be described. The member M5 issubstantially rectangular in shape having an extending portion I5! atthe end of which lever I55 is connected, as has been hereinbeforedescribed. Beneath the member I48 a plurality of electrical switches I52are mounted upon a block l53 which, in turn, is mounted upon the lowerface of the pusher member. Each switch I52 comprises a pair of arms I54and I55 each of which carries a switch point I55. Electrical conductorsI5? are connected to the switches I52 and are anchored in block I51carried upon the lower face of the pusher member.

The opposite end of the pusher member M8 is provided with a relativelylarge central slot or recess I58 which opens at an end of the pushermember. Adjacent the recess 558 on each side thereof are a plurality ofrelatively narrow parallel slots I59. A lug We is mounted upon eachopposite side edge of the pusher member and each lug extends downwardlytherefrom. A plate ISI having opposite recessed corners I52 is pivotallyconnected, as at E53, to the lugs 55. The plate I5I has its rear facechamfered, as shown best at I54 in Fig. 26 whereby said plate may havelimited clockwise motion about pivots I63, as viewed in Figs. 25 and 26.The forward portion of plate IIiI, that is, the portion remote from thepivots IE3, is provided with a plurality of slots I65 corresponding innumber and posi-- tion to the slots I59.

A feeler arm I56 is positioned in each of the slots I65 and intermediatethe length of said arms, said arms are all pivoted to the plate IBI bymeans of pivot rod I51. A strap S63 is secured adjacent its ends to thesides of the pusher member I48 by means of screws I55 and provides adepending sling for supporting ends I75 of the feeler arms I 66. A headIII is mounted upon the end of each feeler arm and is normally adaptedto occupy a position in contact with the lowermost spring arm I55. Theopposite end of the extension of shaft 59. .A casting 20I, Figs. 19, 20,22 and 23, is mounted upon the block I99, said casting having a bore 202which connects into the end of the flexible conduit I98. The bore 202connects into a transverse bore 203 within the casting 20I, said latterbore opening to the face of the casting. .The casting 20! is providedwith a second bore 204 which connects into the flexible conduit I I5which, in turn, connects into block I I4 upon which the sucker tube ismounted. Within casting 20I the bore 202 connects with a transverse bore205 which opens to a face of the casting. The casting 20I is alsoprovided with a transverse bore 206 which extends through the thicknessof the casting and opens at both faces thereof.

The projecting end of the cam shaft 59 extends transversely through thecasting 20!, said casting functioning as an additional bearing support,

for the shaft 59. A plate 201 is adapted to be carried upon the end ofshaft 59, said plate being centrally recessed, as at 208 in Fig. 20, forthe reception of said shaft end. Two diametrically oppositely disposedpins 209 are mounted upon the end of shaft I59 and are adapted to engagein corresponding recesses in plate 201. The inner face of the plate 201is provided with an arcuate groove 2I0 which, as will be hereinaftermore fully described, is adapted to connect bores 253 and 205 during apredetermined portion of the revolution of shaft 59. A housing 2I I ismounted upon the face of casting 20I and functions as a cover for theend of shaft 59 and plate 201 carried thereon. A coil spring H2 isconfined within said housing and bears upon the outer surface of plate201 thereby firmly seating said plate in an air tight manner upon thesurface of casting 20I.

In operation, shaft 59 rotates in a counterclockwise direction asindicated by the arrows in Figs. 19 and 23. As shaft 50 rotates, plate201 is carried around therewith, said plate sliding upon the surface ofcasting 20I. During a portion of the revolution of shaft 59, groove 2 Iin the face of plate 201, bridges the bores 203 and 205 therebyeffectively connecting conduits II and I38 and establishing a conditionof vacuum in the block H4 and sucker tube II2. This phase of theoperation is illustrated in Fig. 19. As the shaft 59 continues torotate, groove 2I0 moves away from bore 203, disconnecting conduits H5and I98. Shortly thereafter groove 2I0 bridges bores 205 and 206 therebybreaking the vacuum in conduit H5 and in the sucker tube II2. This phaseof operation is illustrated in Fig. 23.

The operation described in conjunctionwith the vacuum valve iscorrelated and timed with the movement of the sucker tube H2. When themouth II3 of the sucker tube II2 moves to its closest position beneaththe stack 64 of cards 63, groove 2I0 just commences to bridge bores 203and 205 and a condition of vacuum is established at the mouth of thesucker tube. At this period of operation the separator blade 66 iswithdrawn from its supporting position beneath said stack whereupon themouth of the sucker tube grasps the unsupported edge of the lowermostcard 63. This position of operation is best illustrated inFig. 9. As theoperation is continued, the mouth II3 of the sucker tube movesdownwardly, as illustrated best in Fig. 5, carrying with it thelowermost card 63. At this period of operation, the groove 2I0 isbridging the bores 203 and 205.

After a predetermined downward movement of the'mouth H3, it will benoted that the flanges 35 and 33 carried upon collars 33 and 34respectively which are mounted at the ends of shafts 39 and 32respectively, rotate to a position above the opposite edge of the card63 being carried by the sucker tube. This phase of the operation is bestillustrated in Fig. 7. It will be noted that shortly thereafter theflanges 35 and 35 contact the upper portion of the card being carried bythe sucker tube. At approximately this phase of operation, the plate 201has moved to a position whereby groove 2I0 ceases to bridge bores 203and 205, and shortly thereafter the vacuum in the sucker tube is broken.However, simultaneously, the flanges 35. and 36 bring the opposite edgesof the card 53 into contact with cooperating rollers 2I3 and2l4. Thisphase of the operation isbest illustrated in Fig. 6. It will be notedthat the end edge portions of the card formerly held by the mouth II3 ofthe sucker tube is then confined between the outer surfaces of thearcuate flanges 35 and 36, and the surfaces of rollers 2I3 and 2M,respectively. Thecollars 33 and 34, and the rolls 2I3 and 2M rotate inopposite angular directions as indicated by the arrows in Fig. 6.

With the card 53 confined in this manner, the rear edge of said card isinserted into the slot 923i, such insertion being facilitated by theconfiguration of the elements constituting the forward end of the pushermember IE8. It will be noted that the rearward movement of the card 233between the flanges 35 and 36 and rollers 2 I3 and 2M respectively,continues only so long as the outer surfaces of the flanges are intangent relationship to the rollers 2I3 and 2M. Thereafter, the card ispositioned within the slot WI and the forward edge of said card hasdropped from the flange 55 at the lower portion of the hopper 59, thecard falling to the surface of a platform 2I5.

It will be noted that shortly after the lowermost card is gripped by themouth Ii3 of sucker tube M2, the separator blade 55 returns to itssupporting position beneath the stack 54. It will also be seen thatafter the vacuum in the tube H2 is broken and the flanges 35 and 35 takecontrol of the card, the sucker tube is withdrawn rearwardly from thezone of separation and subsequently is brought to its initial positionbeneath the lowermost card of the stack. It will also be seen that asthe card is pinched or confined between the flanges 35 and 36 and therollers H3 and 2M, cam Icarried on shaft 25, the shaft which carriesrollers 2I3 and 2M, has moved to a position whereby it contacts rollerI'M, initiating the feeling or selecting action accomplished by the arms155. When the card has arrived at this position and the parts are inthis relationship, the card is ready .to be delivered to the printingstation.

Referring particularly to Fig. 16, a rubber roll 2 i3 is mounted uponshaft 53 between the opposite frame members 22. The frame members '22are provided with opposite apertures 2 I1 through which the ends ofshaft 43 extend, the shaft being journalled in bearings 2M and 259.Bearing 2I3 is carried upon a swingable bar 229 (Figs. 3 and 4) which ispivotally mounted at 22! upon frame member 22. A housing 222 is mountedupon frame member 22 and carries a supporting plunger 223 upon which bar229 and bearing 258' are supported, plunger 223 being springpressed byspring 224 carried within housing 222. Similarly, bearing 2I9 is carriedupon a pivotally
